[PATCH 01/08] i386/i386at/kd.c (kdintr): quiet the GCC warning about signed overflow

[Marin Ramesa]

WIDTH_KMAP is the number of columns in the key_map table. Check
if char_idx is less than WIDTH_KMAP and break the for loop if
that is not the case.

i386/i386at/kd.c (kdintr): Break the for loop if char_idx is larger or equal to 
WIDTH_KMAP.
